Simultaneous 1080p60 SDI capture

Hi,

What product would be best for capturing 2 1080p60 SDI inputs simultaneously. I heard that some products claim they can achieve this but they can't in practice. Alternatively can you recommend something that can do 1080p30, in case the other item is too expensive.

Something that can also capture HDMI would be a big bonus, but as far as I know, 2 3G-sdi input capture concurrent with 1 HDMI input capture isn't possible on one device.

Thanks,
Dan

Our Decklink SDI 4K Pro PCIe card will capture 4K at 60P as it supports 12G speed so could be configured for your application.

Do you want a hardware or software based solution? Do you want a lossless codec, or h264/265?

If software, sure you could use any number of interface cards (the DL Quad) and combine that with ToolsOnAir Just:In Multi -- capture all 4 to any flavor you like. Softron also has MovieRecorder. vMix and Wirecast will capture 4 streams and do ISO recording. Beefy machines needed in any of these scenarios.

Hardware devices, COnvergent Design makes a 4ch device that records ISO, switches, AND makes a multiview. Extron makes the SMP 351 that will record any 2 sources to .mp4 and also make a 2up composite and spit out to a stream. Datavideo makes a new unit that will stream/record up to 4 sources.

Define your workflow and your pocketbook then you can narrow down.

Hello Daniel. From Blackmagic, only the Decklink Duo or Decklink Quad will capture 2 or more 1080p60 signals at the same time. No HDMI so you would need to use a converter.

Does the fact it can capture 4k60 imply that it can capture 2 1080p60 sources? I'm new to this so any advice is appreciated.

I'm going to be honest Roger, I don't understand the majority of the words you've used here . I'm very new to live production. Essentially I have 2 1080p60 cameras with SDI output, and one PC input via HDMI that I all want to capture on a single PC and mix them with OBS as cost effectively as possible. I'm open to any methods I can look at to achieve this. As a side note this is for an esports stream.

Thanks for clarifying that Gary! Am I right in thinking the Decklink Duo 2 could capture up to 4 1080p60 sources, meaning I could use that in combination with a converter?

Does the fact the Decklink 4K Pro can capture 4k60 imply that it can capture 2 1080p60 sources? I'm new to this so any advice is appreciated.

No, the DeckLink 4K Pro only has a single video input channel. It has 2 SDI input connectors to support dual link SDI (where a single video signal is split over two SDI cables), but this is still just a single video input.

As Gary mentioned, the only cards that currently support multiple independent video input signals are the DeckLink Duo 2 and DeckLink Quad 2 cards.

Am I right in thinking the Decklink Duo 2 could capture up to 4 1080p60 sources, meaning I could use that in combination with a converter?

Yes, each port on the DeckLink Duo 2 is separately configurable as either an input or an output (via the Desktop Video utility software). So you could configure the card for 4 inputs, or 4 outputs, or 2 inputs and 2 outputs, depending on your needs.
